Why galvanometer show one side deflection in meter bridge experiment?

there may be two possible errors
1) it may be bcz of the change in the polarities while connecting the circuit
2) the connection may not be tight

What is the square root of the meter of square?
The square root of meter squared is meter.
What Is 14 Cm In A Meter?
0.14 m 1 meter = 100 centimeters 1 centimeter = 0.01 meter
How many square meters in a meter?
none. 'A meter' is linear.
What is 1 meter to the third power?
1 cubic meter.
Are mm bigger then m?
No. A millimeter, or mm, is smaller than a meter, or m. A millimeter is actually a thousandth of a meter, so it is MUCH smaller than a meter.
What is steady deflection?
When battery key and galvanometer key are pressed together ..throws comes out on the meter scale which goes on either side and stop there..that is steady deflection...
What is a description of the principle of a meter bridge?
it work on the principal of balanced wheat stone bridge ..i.e the reading of galvanometer shows 0 ..
What happens to a galvanometer when a magnet is flicked across the coil?
It should deflect to the left (negative) based on the experiment I did a few days ago in lab but I could be wrong. ============================= Doesn't that depend on which end of the coil goes to which end of the meter ?? After you finished the experiment and made note of the meter's deflection, you could leave everything exactly as it is, but get up, walk around to the other side of the table with the magnet, insert the S-pole into the other side of the coil, and I guarantee the meter would deflect in the opposite direction. The configuration is not adequately specified in the question.
What is the deflection sensitivity of a cathode ray oscilloscope?
It is the deflection on the screen (meter) per volt of deflection
Why is the lamp and scale arrangement in a ballisitics galvanometer at a distance of 1 meter from the galvanometer?
for the convenience of calculations
What kind of meter is created when is shunt is added to a galvanometer?
A galvanometer with a low resistance shunt in parallel makes an ammeter.
How do you convert galvanometer to an ohmmeter?
"An ohmmeter is an electrical instrument that measures electrical resistance, the opposition to an electric current."The unit of measurement for resistance is ohms (Ω).It is useful device for rapid measurement of resistance. It is consist of galvanometer and adjustable resistance Rs of known value and a cell connected in series. The resistance R to be measured is connected between the terminals.The series resistance Rs is so adjusted that when the terminals are short circuited i.e., when R = 0, the galvanometer gives full scale deflection. So the extreme graduation of the usual scale the galvanometer is marked 0 for resistance measurement. When terminals are not joined no current passes through the galvanometer and its deflection will be zero . Thus zero of the scale marked as infinity. . When R is not infinite , the galvanometer deflects to some intermediate point depending on the value of R scale can be calibrated to read the resistance directly.
Construction of ohm meter and megger?
Ohm meter is basically a series combination of resistances and galvanometer and source of current .Used to determine unknown resistance.
What is coil galvanometer meter and its application?
Moving coil galvanometre is a device which is used to detect current in a curcuit.
What is full scale deflection?
Full Scale Deflection is equal to the max value on a scale or meter. If a thermometer reads from -20 degrees to +100 degrees, the full scale deflection = 100 degrees and the range = 120 degrees
What does electromagnetism have to do with galvanometer?
A galvanometer is a simple meter that detects the flow of current. A current flowing in a wire causes magnetism around the wire. This is called electromagnetism. Like poles of a magnet repel and opposites attract. The Galvanometer uses these principles in order to move a pointer across a scale.
How do you make an improvised voltmeter?
You need to build a galvanometer first; this is a sensitive current meter. Simple designs involve wrapping loops of wire around a compass. Then select a relatively high resistance and make a series circuit in this order: 1) voltage source 2) resistor 3) galvanometer The small current flowing through the circuit (due to the high resistance) will be noticeable in the deflection of the compass needle. The resistor should be chosen to limit the current in the circuit so that the deflection is noticeably different for different applied voltages. If the resistance is too small, all voltages will cause a full deflection of the compass needle. If the resistance is too large, there will not be any noticeable deflection for your choice of voltages. Higher voltages should cause greater deflections. http://madlabs.info/galvanometer.shtml hope that helps, M
